Improved ditching-machine



JOHN MARSH, or SENECA, ILLINOIS.

Letters Patent No. 83,296, dated October 20, 1868; antedated September 28, 1868.

IMPROVE!) IDITGRIN'Cai-MLACHIIIN'El Beit known that l', JOHN MARSH, of Seneca, in the county of Grundy, in the State of Illinois, have invented anew and improved Ditohing and Grading-Machine; and I do hereby declare that the following is a fullfand exact description thereof, reference beinghad to the accompanying drawings, and to? the letters of reference marked thereon.

a ditching and grading-machine, supported on two main wheels, of which one is larger than-the other, the one on the plpw-sid'e being the largest, so that the' machine, in making a ditch, will assume a level position,

or" nearly so.

My invention also consists in so simplifyingthe gearing, that a single shaft will drive the apron direct from the main wheel.

My inventioni'urther donsists in providing a toggle- 1 joint to the shaft drivingthe' apron, so that the latter can be raised or lowered at will while at work. l

To enable others skilled in the. arts to make and use m invention I will roceed'to describe its construction y p beam K passes, and whichallows the forward end to and-operation.

Figure 1, in the drawings, is a vertical plan. Figure 2 is a horizontal plan.4

' 'Figure 3 is asection through a. b, lig. l.

I construct a name, A, of timber, across which passes the Vaisle-tree B, having on it the two main wheels O andO. l

' The wheel (l is smaller than the wheel C', in order that the machine, when working or digging out a ditch,

may beheld morev level. By this meas, also, a narrower machine can be used 'than if the two wheels were alike. y

The wheel'C has cast or bolted to it, a bevel-oog rim, D, into which meshes a bevel-pinion, E. y This pinion E slides onja shaft, F, by means of a lever, Gr, operated by hand.

a over it, may be scooping in the middle, so as to keep the The nature of my invention consists in construct-ingr:`

dirt better together, and prevent it om rolling oii on each side.,

The frame J, which supports the apron I, is movable at each end, and 'to give the apron its required motion in its different positions, the shaft F has two universal joints, one at F and one at F".

The plow K is of the-ordinary kind, and has at the forward end of the beam a clevis, K', with notches, so`

that the pitch of the plow can be graduated. p The lever L enables the driver to raise the plowK out of the ground, and also to raise the apron I-rom the ground.

At the same time the driver is enabled to give press.- ure to the plow K, by lifting up the forward end of the` lever L. I,

A protecting-shoe, M, is adapted under the lower4 end of the apron-frame J, to prevent the apron I from wearing np'on the ground.

The plow K is braced by a double brace, N, which slides along a guide, O, and `by means of which the inclination of the plow can be regulated.

There is also a brace, l?, through which the plowsuch a manner that it canmove up and down, but not sideways.

A standard, S, is provided, with pins to hold the levers Gand L.

There is also a seat, 'I, `for the driver.

What I claim as my invention, and desire to'secure by Letters Patent, is-

1. The combinationof the lever` G, shaft F, roller H,

, Y and apron I, with the lever L, plow K, apron-frame The shaft F drives the .toothed roller H, over which passes the apron I. y

J, and shoe M, substantially as and for the purpose described.

2. The combination of the wheels O Q', frame 'A, beam K, double brace N, guide O, and brace l?, substantially as and for the purpose described.
